Edward Weevil, or "Whitebeard Jr.", is a pirate claiming to be the biological son of the now deceased Emperor Edward "Whitebeard" Newgate. He is the son of Miss Buckin, the self-proclaimed lover of Newgate. He served as one of the Seven Warlords of the Sea, whom he joined sometime during the two-year timeskip, and did so until the Warlords' dissolution.
Weevil was first mentioned by Marine commodore Brannew in a discussion of the current Warlord ranks to several high-ranking Marine officers, but was not explicitly named until after Donquixote Doflamingo's defeat.
Weevil's powers have been praised by Borsalino who compared his abilities to that of a younger Whitebeard, his alleged father. He was able to single-handedly defeat 16 pirate crews affiliated with Whitebeard, including the A O Pirates. When the Marines attempted to arrest Weevil after the Seven Warlord was abolished, Weevil completely wiped out the all the Marines sent to capture him. When he later appeared on Sphinx to protect it, the Marines there quickly retreated in fear of the former Warlords power. While he was no match for Admiral Ryokugyu, he at least survived the brutal Admirals attack.
Like his alleged father Whitebeard, Weevil wields a naginata as a weapon of choice.
Weevil possesses the ability to use Busoshoku and Kenbunshoku Haki.
